Custom Pultrusion Mould

we provide a comprehensive service of custom pultrusion molds, designed to meet the specific needs of our clients in FRP industry. 

The pultrusion die is crucial in the production of composite materials. It decides the size precision and technical quality of FRP profile and the efficiency of pultrusion process. 

Our factory has engaged in pultrusion field for more than 20 years accumulated rich experience. This enable us capable of mold design 

1. Proper size of mould cavity: a good estimate in shrinkage rates from the fomula of pultrusion material decides if the sizes of intended profile can meet the tolerance requirement. 

2. Good design in section size: Too large sized pultrusion mold will increase the cost while too small sized mould may not work properly in actual production. Our experience in mold design is not only from the design cases we did, but also from the production of FRP profiles for our customers. Yes, we are not only FRP die manufacturer but also user of it, we have been pultruding profiles for customers. This is a difference from others.

3. Material selection: this is very important as it affects durability and performance of pultrusion die. It includes not only the selection of steel type but also the surface finishing.

4. Parting surface design: minimizing parting surfaces can ensure a tight seam and facilitate easier demolding. For seamless mold this step is not necessary.

5. Versatile design options: We offer a wide range of design options for custom molds, including various shapes and sizes (flat strips, tubes, rods, or complex geometries), different resin types (unsatured polyester, epoxy) , fiber types (carbon fiber, glass fiber), if with injection or not, if seamless dies or not.

You can send us your requirements, or drawings of intended profiles, then we will make a detailed plan for you.
